Hi everyone,
I have an old setup that I would like to upgrade, cheaply if possible (around 500E)

 

What I have :
Video source : macbook air (connected to the video projector in HDMI via Display Port), sound send via airplay
Airport : connected to the amplifier via jack on 2 inputs
Amplifier : Yamaha RX-V350 (configured in stereo mode with 5 speakers and the subwoofer...)
Vidéoprojector : LG AF-115
5.1 System: JAMO S 606 HCS 3 + titan mosscade 7.4 (wired to the amplifier)

 

What I need :
To have battery powered wireless surround speakers (because of the room)
Go to real 5.1 and be able to listen music (exit soundbar I guess)

 

What I plan to do :
Video source : macbook air (connected to the video projector in HDMI via Display Port), sound send via Wifi to the AV receiver
AV Receiver : would dispatch via BT or Wifi to 2 surround speakers and via wire to the other speakers and subwoofer
Vidéoprojector : LG AF-115
5.1 System: JAMO S 606 HCS 3 + titan mosscade 7.4 (wired to the amplifier) + 2 bluetooth surround speakers (I have already a Libratone zipp, so maybe I'll buy another ?)

 

So :
Is it a brillant idea ? ;)
Does an AV receiver can mix BT (or Wifi) and wire transmission ?
Do you have an entry level model that'll do the job ?

 

Many thanks for your help,

 

Romei.
